Downloading PDF Files Using playwright-python

Are you trying to download PDF files rendered in a browser using playwright-python? If so, you may have encountered some challenges, especially when no direct URL is available for the file. This can leave you frustrated if you can’t seem to find a way to access the document. But fear not! In this guide, we'll guide you through a solution to effectively download those elusive PDF files.

Understanding the Problem

Many developers run into the issue of needing to download PDFs that do not present a straightforward URL for access. Instead, the PDF may be displayed in the browser in a way that doesn’t provide a direct link. This makes it impossible to simply use libraries like requests to fetch the file.

Common Symptoms:

This simple switch can often resolve any download issues and help you successfully acquire your PDF files.
